The new HR700 horizontal resaw offers modularity and larger capacity for timber processors.
The new Wood-Mizer HR700 furthers Wood-Mizer industrial sawmilling range with a larger capacity, modular, multi-head resaw. Its modularity makes it easy to expand from one to a maximum of six heads. In its maximum configuration, the HR700 converts large cants into six boards and one slab in one pass.
Cant capacity for the HR700 is 400mm wide by 400mm high. The shortest length that can be processed is one metre. Each cutting head is equipped with a 15kW electric motor, or optionally with an 18.5kW motor.
The resaw can be installed as a standalone unit, but has been designed to integrate into Wood-Mizer’s current SLP log processing lines. The HR700 uses the same size blade as all other machines in the SLP lines, standardising ordering for customers to one blade size.
The basic HR700 module includes two headsas standard. To extend the resaw, all that is needed is to add another two-head module and install a longer conveyor belt. The modular design makes transportation easier and less costly, as well as giving businesses the option to scale up their resaw capability as their business grows. For returning unfinished cants back through the resaw, roller tables are available for a manual cant return system.
A separate control stand holds all controls for the resaw. Standard, head height is positioned with a manual screw. Optional setworks with electric up/down are available, which increase speed and precision when adjusting the heads to produce different sized timber. Centralised blade tensioning for each two-head base makes the blade change process more efficient.
The twin-track steel belt conveyor provides a solid and durable surface that fully supports the entire cant width. Belt speed is variable up to 20 m per minute. Heavy, powered rollers stabilise and feed the cants through the heads during sawing. This makes it easier to process short cants or material with internal tension. A pneumatic sensor automatically raises the rollers to accommodate incoming cants. The roller speed is synchronised with the conveyor belt speed, providing more precise cutting, especially for thin boards.
To support expanding the product range into larger machinery, Wood-Mizer completed construction of an additional production hall in early 2014.
"We want to be a provider of sawmilling equipment to the timber industry at all levels," shares president and CEO Richard Vivers. "We have diversified our geographical presence and our products. The expansion of our European headquarters gives us a solid base to move up to the next stage in the sawmilling industry globally."
